A. Answer the following:
1. If two angles are complementary, what is the sum of their measures?
2. If the measure of an angle is equal to the measure of its complement, what is the measure of the
angle?
3. If angle ABC = 160 what is the measure of angle ABD if they are supplementary angles?
4. If measure angle XYZ is 46, what is the measure of angle WYV if they are complementary angles?
2.


Sagot :

Answer:

1. 90°

Complementary angles equal to 90° when added.

2. 45

Angle = 45°

Complement = 90 - 45 = 45°

Sum = 45 + 45 = 90°

3. 20

Supplementary angles have a sum of 180° when added.

180 - 160 = 20

4. 44

90 - 46 = 44
